This lesson begins the study of salvation history. God created the world "out of nothing" in wisdom and love, to show forth His glory and share His truth, goodness and beauty with His creation. He created an invisible (angelic) world and a visible (earthly) world. Man is the crown of creation. The Sabbath is the sign of the covenant between God and man; the world is a macro-temple; Eden is a sanctuary, and Adam is high priest of humanity.
